The Single Electricity Market Committee (SEMC) decision SEM-15-071 “Process for the Calculation of Outturn Availability” was published on 29 September 2015. The decision applies to both transmission and distribution connected Centrally Dispatched Generating Units (CDGUs) and Controllable Power Park Modules (PPMs) (SEM Dispatchable and Controllable Generation Units) which are disconnected as a direct result of a transmission outage scheduled by the TSO. Outages on the distribution system are not related to the decision paper.

The Single Electricity Market Committee (SEMC) decision SEM-15-071 “Process for the Calculation of Outturn Availability”, published on 29 September 2015, required that the TSOs establish a forum which will be responsible for publication of separate ex-ante outage plans for Northern Ireland and Ireland. The SEMC decision also required that the ex-ante outage plans for each outage season be sent to the RAs for review.
